A single-wheeled chariot in red and white which represents Lord Surya’s chariot is drawn on the Ratha Saptami day. The Rath or Ratha Saptami Kolam is drawn in front of the Puja happening space. Usually, the puja is conducted near the chariot Kolam. Some people prefer to draw a small Rath Kolam on a wooden piece and place it outdoors and perform the pooja. Here are examples of a few Ratha Saptami Kolams. These are only examples to give an idea.
